I have been using Tamiya acrylics to to small detail painting. I have a bunch of their clears, also the X22 which I use mostly as an adhesive and some blacks and silvers. I will give the Vallejo line a try. Anything I paint is very small, everything else gets sprayed.
I use the clears over TS-30 Silver Leaf on things like steering wheels, fans, shift knobs, side marker lights.
